Police say Parrinello and another man, Carmello D'Alessandro, got into an argument in the parking lot of Canyon Springs School while picking their kids up after their first day of classes in August 2012.

Parrinello told D'Alessandro to meet him at a nearby Walmart, where they would settle the dispute "like men," witnesses told police.

Parrinello went to the store, but D'Alessandro did not. Police said Parrinello hunted D'Alessandro down with his Ford Excursion and ran him over, killing him.

Authorities later found Parrinello at a park where he worked, but he had wiped his car clean. Tests done on the car would later show blood residue, records show.

D'Alessandro's family was not present at the sentencing on Friday because they were too devastated and could not bring themselves to come, said a family friend speaking on behalf of the family.

About 15 people showed up in support of Parrinello. His father, Michael Parrinello, told Maricopa County Superior Court Judge Bruce Cohen that locking his son up would not benefit anyone.

"He's not a violent person," Michael Parrinello said.

The elder Parrinello said his son obtained his GED in prison and was baptized last week.

"He's a very good person, a good man," he said. "He works hard."

The family also submitted photos of Parrinello that they believed depicted him as a caring family man who only wanted to protect his family.

Parrinello's ex-wife and former step-daughters also addressed the court, describing Parrinello as a physically and emotionally abusive man who drank too much and only brought pain to their family. They, along with prosecutors and the D'Alessandro family representative, asked for the maximum sentence of 25.5 years: 22 years for second-degree murder and 3.5 years for leaving the scene of an accident.

Prosecutor Stephen Walker said probation was not appropriate for leaving the scene of the accident.

"If it wasn't premeditated, it was as close as it gets to premeditated," Walker said.

Parrinello's defense attorney told the court that Parrinello began taking prescribed doses of testosterone, which has been linked to aggression, shortly before the incident occurred. The hormone, coupled with a brain injury from a previous motorcycle accident, affected Parrinello's aggression and impulse control, but he has since taken anger-management classes, his attorney said.

The defense told the court that D'Alessandro was under the influence of methamphetamine the morning of the incident and pounded on Parrinello's door looking for a woman who was also Parrinello's babysitter. Parinello's defense said D'Alessandro went to the school to confront the woman, which led to the incident.

Parrinello read a prepared statement and apologized for his actions.

"My family, as well as many others, were deeply affected by what took place," he said, adding that he should have called police when the dispute first started and he was not intending to kill anyone. Parrinello said the prescription testosterone was no excuse for his actions but believed it affected him that day.

Parrinello also apologized to the people who had to stop to help D'Alessandro after he was left in the street. He said he planned to make good use of his time in prison by furthering his education and serving others.

While Cohen listened to the family of Parrinello's ex-wife, he said he would not take their claims about Parrinello's character into consideration because the sentencing was for the incident involving D'Alessandro. He also said he would not take into consideration D'Alessandro's character because, although D'Alessandro was under the influence of methamphetamine in the morning of the day the incident took place and had not always made the best choices, he did not deserve to be hit by a vehicle and dragged 40 feet through the street.

Cohen said there were aggravating factors in the case, calling Parrinello's actions callous.

"You guaranteed his death by driving away," Cohen said.

Amy Anglin, Parrinello's ex-wife, said she was pleased with the sentence, calling it "well-deserved." Parrinello's family declined to comment.
